The P{αTub84B(FRT.CD2)lexA::GAD.A} construct contains the αTub84B promoter fused to an FRT site, followed by CD2 coding sequence and an α-tubulin trailer, followed by a second FRT site and sequence encoding a lexA::GAD driver.
The αTub84B promoter is separated from sequence encoding a lexA::GAD driver by an FRT cassette that contains CD2 coding sequence and an α-tubulin trailer.
